A Research on the Theory and Technology of Trusted Transaction in Modern Service Industry.

This paper mainly discusses the theory and related technology of trusted transactions in modern service industry. Three prohibition principles of trusted transactions in modern service industry are summarized by lucubrate. Through detailed research on the blockchain technology, especially the Consortium Blockchain, we find that its innovation and characteristics meet all the requirements of trusted transactions. After that, we discuss the cryptography and computer principles and technologies behind the three prohibition principles of blockchain supporting trusted transactions in details, implemented on which the smart contract technology is analyzed. On this basis, we put forward the overall framework of trusted transaction based on blockchain technology, and take the e-commerce platform as an example, and the basic design on multilink and microservice framework. Ultimately, we conduct study on big data credit investigation and credit evaluation for trusted transactions under the blockchain system, and make a preliminary discussion on the dynamic penetrating supervision model based on big data of blockchain transactions.
